Articles related to the American Mafia, a highly organized Italian-American criminal society and organized crime group. The terms Italian Mafia and Italian Mob apply to these US-based organizations, as well as the separate yet related Sicilian Mafia or other organized crime groups in Italy, or ethnic Italian crime groups in other countries. These organizations are often referred to by its members as Cosa Nostra (Italian pronunciation: [ˈkɔːza ˈnɔstra, ˈkɔːsa -]; lit. 'Our Thing') and by the American government as La Cosa Nostra (LCN). The organization's name is derived from the original Mafia or Cosa Nostra, the Sicilian Mafia, with "American Mafia" originally referring simply to Mafia groups from Sicily operating in the United States. The Mafia in the United States emerged in impoverished Italian immigrant neighborhoods in New York's East Harlem (or "Italian Harlem"), the Lower East Side, and Brooklyn.
